You can't do research without data. But what kind of data will help you answer your research question? Where can you find that data? And how much data do you need? If you're doing doctoral research, particularly in the social sciences, arts, or humanities, this book will help you answer those questions. It offers an overview of traditional and innovative methods of gathering quantitative, qualitative, secondary and primary data. The book also outlines the pros and cons of devising your own method of gathering data, and lists a range of resources for further exploration of the methods that interest you most.
